The Orbeon Forms Blog

Web 1.0 applications typically perform client-side validation (when they do it at all) with JavaScript libraries, often checking only minimal aspects of the form. Upon submitting the form, server-side validation is performed as well (you can never trust the client), and in case of error the filled-out form is returned... More

John Boyer (of IBM and co-chair of the W3C XForms Working Group, of which Orbeon is an active member) mentions on his blog two new publications from the XForms Working Group: A new collection of errata for XForms 1.0 Second Edition was published on July 12, with welcome precisions on:... More

As a web application developer (or just as a regular human being), you have probably wondered at some point: why do online PDF documents open in my HTML browser window?

</param> </param> </param> </embed> </param> With XForms 1.0, it is not possible to differenciate between a submission error due to an invalid form (or with required-but-empty values) and a submission error due to, for example, a network issue, an HTTP 404 error response, etc. XForms 1.1 is adding many submission-related...

It looks like software developers in particular love to hate software, any software. Well, almost any: FireBug seems to be loved by everyone.
